Evaluation and public preference heterogeneity of desertification control in Xinjiang
The evaluation of economic value of desertification control,which includes the consideration of public preferences,is an important basis for formulating scientifical desertification control policies.By examining the evaluation of desertification control in Xinjiang,this article employs the choice experiment method to investigate public willingness to pay and preference heterogeneity for desertification control,and introduces a latent class model to analyze the factors contributing to heterogeneous preferences among respondents.The results show that there is significant heterogeneity in preferences for desertification control among the general population of Xinjiang.Specifically,respondents can be divided into three latent class,which is named:preference-normal type,environment-friendly type,and price-sensitive type,respectively.Among them,the largest proportion of respondents(68.17%)belongs to the preference-normal type,which is significantly higher than those of the environment-friendly type(19.86%)and price-sensitive type(11.97%).The respondents categorized as preference-normal type and environment-friendly type exhibit higher willingness to pay for desertification control attributes.The results also reveal the relationship between public preferences and their socio-economic and environmental attitude characteristics.Specifically,respondents who are younger and with a higher level of concern and control consciousness tend to improve desertification control attributes,whereas respondents with a lower level of concern,control consciousness and income show a lower willingness to pay.The findings are helpful to provide theoretical basis and technical support for improving the current and future desertification control and management,which contribute to enhancing the rationality and feasibility of policies or projects.
